Was just driving along today, and had to slow down because of traffic in front of me. Honestly, I looked down and the speedometer was hovering at 0 mph, and not really moving anywhere. Then, at the same time as I'm driving, the rpms are racing at like 3 and 4 when I know I was only going 25-30 mph. Pulled the car over, and waited a few minutes. Turned back onto the road, and same thing happened. Just drove home, and I"m so upset. Just last week I had two new tires put on, and had the car aligned. It was driving perfect. Anyone, have any idea what this issue could be. BTW, the car wasn't overheating.
